SAN MARCOS  One person died after a car slammed into two trees Thursday on East Mission Road in San Marcos, and the driver may have been racing, the Sheriff’s Department said.

The crash occurred east of Woodland Parkway, a few blocks east of Mission Hills High School, about 2:40 p.m.

A white Scion TC was heading west on East Mission Road at a high rate of speed when the car lost traction on a curve, sheriff’s Deputy Agustin Rosas said. The car went over the curb and struck one eucalyptus tree, then hit a second tree before coming to rest on a sidewalk.

The driver’s side had major damage, the hood was nearly ripped off, and the top of the car was crushed. The driver was pronounced dead at the scene.

Authorities did not release the victim’s gender or age.

Witnesses said the Scion may have been racing with the driver of a dark-colored vehicle, Rosas said.
